Emulsion coagulant, and flat tire repair kit using same

Abstract

An object of the present invention is to provide a novel emulsion coagulant having excellent coagulability used in a tire puncture sealing agent, and a tire puncture repair kit that uses the same. The present invention is an emulsion coagulant comprising magnesium oxide and a silane coupling agent and a cellulose and/or magnesium hydroxide, wherein a mass ratio of the magnesium oxide to the silane coupling agent is from 100:0.5 to 100:15; and a tire puncture repair kit that uses the same.

What is claimed is: 
     
       1. A tire puncture repair kit comprising an emulsion coagulant and a tire puncture sealing agent, the emulsion coagulant including magnesium oxide and a silane coupling agent, and at least one selected from the group consisting of a cellulose and magnesium hydroxide, a mass ratio of the magnesium oxide to the silane coupling agent being from 100:0.5 to 100:15. 
     
     
       2. An emulsion coagulant comprising magnesium oxide and a silane coupling agent and at least one selected from the group consisting of a cellulose and magnesium hydroxide,
 wherein the silane coupling agent is at least one type selected from the group consisting of a compound having a methacryloxy group and at least one type selected from the group consisting of a dimethoxysilyl group, a trimethoxysilyl group, a diethoxysilyl group, and a triethoxysilyl group, tetramethoxysilane, and tetraethoxysilane, a mass ratio of the magnesium oxide to the silane coupling agent being from 100:0.5 to 100:15, wherein a mass ratio of the magnesium oxide to the at least one selected from the group consisting of a cellulose and magnesium hydroxide is from 100:40 to 100:400. 
 
     
     
       3. The emulsion coagulant according to  claim 2 , wherein the magnesium oxide and the silane coupling agent and the at least one selected from the group consisting of a cellulose and magnesium hydroxide are packaged in a batch. 
     
     
       4. A tire puncture repair kit comprising the emulsion coagulant described in  claim 2  and a tire puncture sealing agent.
